Poor Service MTN

My wife upgraded on 29 April 2019. Seems phone got delivered to the wrong person, long story short, contract was cancelled and is now re-done. Today is 29 May 2019, phone will be delivered later this afternoon ( hopefully) . My problem is that the free data etc all expired yesterday. I called the call centre yesterday to confirm when data will expire and she said today. We have been clients of Mtn for many years and until now did not have reason to complain. This is the 1st time things have gone wrong and now I know that if things go wrong, MTN is not interested, or able to solve a query. From having to deal with rude call centre agents, being told that supervisors/managers do not want to speak to you, MTN have made it know to us how they value us as customers
